To all whom concern: I

Be it lmown that I, ARTHUR A. Fnms'mmi,

Chicago; in the county of Cool; and ofvl'llmo'is, have invented certam new and useful Improvements inTnre-Rim Tools,- or

; which the following is 'a specificatim invention relates to tire tools adopted for breaking thelocksof demountable "and contracting the rims as to permit removal and replacement of tires.

, its normal locked position.

to engage both flanges of a tire rim, and by reason of the pivotal connection of these hooks through the too be r 25 the hooks are capable of being moved toward and from each other to accommodate the hooks to rims of various widths.

In Fig. 1 I have illustrated the position of my improved tool for breaking the rim lock and initially overlapping the rim ends. For this purpose the hook members 23 are engaged beneath the flanges of the rim adjacent to one end thereof while the shoe 15 is disposed in substantial alinement with the handle 13, the sharpened ends being in serted between the abutting ends of the rim. The handle is now swung in a counter clockwise direction, thereby pulling upwardly on the books 23 and forcing the points of the shoe downwardly between the rim ends with the result th at the Wedge-shaped shoe points force the rim ends apart sufliciently-to disengage the locking member 9 from the locking member 8, whereupon the end of the rim engaged by the books 23 is lifted and carried oger amt" the opposed .end. When this position has been reached the tool will be repositioned so that the shoulders 18 will abut against the rim locking member 8 when the shoe lies flat against the inner face of the rim and thehook members will be moved backwarr ly on the opposed rim end until the toe bar 25 abuts against the opposed end of the locking member 9. Upon swinging movementof the handle 13 in a counter clockwise direction about the pin 17 as a pivot the end of the rim engaged by the hooks and the toe bar will be pulled over the end engaged by the shoe until the ends have been sufficiently overlapped, in which position the free end of the handle 13' will be close enough to the rim to permit the hook 14 to be engaged with one of the rim .flangcs'and thereby lock the rim n contracted position. The position of the parts when the rim has been partially contracted is shown in Fig. 2.

After the-tire has been removed and replaced, the tool is. positioned with respect to the rim as shown in Figs. 3 an'd 4, for the purpose of forcing the rim ends backwardly, or, in other words, to expand .the rim into Referring nowparticularly to Fig. 3, it will be observed 11118-13 the hook members 23 each comprises a 'pair ofhooks which are (lcsigrmted 27 and '28, respectively. The hooks 28 are short er than the hooks 27, that is, they do not extend as great a distance from the pivotal connection with the links 21 as do the hooks 27. When the tool is used for expansion. purposes, that is to expuurl therim to normal. position. the hooks 2 are so-fmsitioued that the shorter hooks 2R abut against the end oi. the. outer portion of the rim, while the hooks 27 un derlie the rim flanges. The shoe 15 is positioned over the toe bar 25 and engages the locking member 9 on the inner end of the rim With the parts positioned as shown in Figs. 3 and 4, the handle 13 is swung in a counterclockwise direction about the pivot pin 17. The shoulders 18 of the shoe push the inner end of the rim to the right, while the books 28 engaging the end of the outer portion of the rlm pull thatend to the left. The resultantefl'ect of this combined pushing and pulling action is that the rim ends are brought back to their original position and the tongue 11 of the lockin member 9 engages in the recess 12 of the coking member 8, thereby locking the rim ends fixedly together.

It will be manifest from the foregoing that my improved tool is designed to separate the abutting ends of the rim so as to break the lock, and then pull one end over the other into partiall; overlapped relation. The tool is next manipulated to further overlap the ends so as to release the tire from the rim and the rim is locked in contracted relation until the tire has been removed and replaced. Upon release of the hook 14 from the rim, the rim ends return to partially overlapped relation, whereupon the tool is again. applied in the position shown in Figs. 3 and 4, and upon manipulation of the handle,

the rim ends are forced apart until they are brought back to their original abutting relation with the lock members interengaged.

My invention and its mode of operation should be understood without further description and it should be obvious that the details of construction illustrated and described are capable of considerable modification and variation without departing from the essence of the invention as set forth in the following claims: I

I claim:

1. A tire-rim tool, comprising a member having a bifurcated and provided with. a pair of shoulders, the extremities of said bifurcations being sharpened for insertion between the abutting ends of a rim, a handle to one end of-which said member is attached, and a pli'lrul'ity of rim-engaging devices cognectcd to said handle intermediate its on s.

2. A tire-rim tool, comprising a handle, a shoe, and a air of book members connected with sai handle, each consisting of a plurality of hooks of different lengths, the shorter hook being adapted to engage the end of a rim when the longer hook is-engaged beneath the rim flange.

3. A tire-rim tool, comprising a handle, a.- shoe pivoted thereto, a pair of links connected to the handle, and a hook member carried by each link, each book member consisting of a long hook and a short book adapted to engage the outer euge and the (connections between saidhook members anti end, respectively, of a tire-rim flange. said handle whereby, upon manipulatimii of i .4. A tire-ri1n-tool, eomprising a handle, a said handle, the hook members pull upon one shoe shaped for thrust engagement with a end of the riniwhile the shoe pushes againet rim lock, hook melnlwrs comprising porthe locking member of the other end to bring Hons of dill'erenl lengths shaped to respeethe rim ends into abutting relation with lively engage beneath a rim flange and'to each other. i 4 engage the end of an overlapped rim, and ARTHUR A. FRIESTEDT.
